Frequently Asked 'Generator Maintenance' Questions

How often should a generator and automatic transfer switch be serviced?
Manufacturers recommend servicing your generator at least once a year, or every 100–200 hours of operation, whichever comes first. Annual service before storm season keeps the engine, electronic controls, and Automatic Transfer Switch (ATS) working together reliably. Regular maintenance also prevents component wear from turning into a failure right when you need backup power most.
A professional service combines mechanical and electrical care. It includes oil and filter changes, spark plug checks, and a full set of electrical diagnostics: testing battery voltage and terminals, inspecting the voltage regulator, confirming proper ATS operation, and running a load test to verify the generator produces stable, correct voltage and frequency for your home’s circuits.
That’s normal. Standby generators run a short self-test, or “exercise” cycle, usually weekly or bi-weekly, for about 5–20 minutes. This keeps the engine lubricated, charges the battery, and confirms the system is ready to start during an outage. If your generator stops running its exercise cycle, runs longer than usual, or shows a warning light afterward, it’s time for a service call.
Standby generators are permanently wired into your home’s electrical panel through the ATS. Only a qualified professional should test and inspect these high-voltage connections, which protects against dangerous backfeed onto utility lines. DIY electrical work on the system can violate electrical code, void the manufacturer’s warranty, and damage sensitive components like the control board or voltage regulator.
Call for service right away if the control panel shows a system alarm or service light, the unit fails its weekly self-test, or you notice low or fluctuating voltage under load. Other red flags include the ATS failing to switch over, excessive exhaust smoke, fuel or oil leaks, and unusual grinding or knocking noises from the engine or alternator.
